The iPhone has become one of the most popular cameras in the world, and the iPhone 5s offers the best image quality of any iPhone to date. It is also filled with advanced features: two flashes, built-in high dynamic range (HDR) imaging, a burst mode, and a video mode that shoots 120 frames per second slow motion.

In this course, photographer, author, and educator Ben Long explores the iPhone 5s as a serious photographic instrument, using its built-in features as well as a hand-selected collection of accessories and apps that will extend your iPhone power. He details the basics of shooting with the iPhone, and then delves into more advanced camera capabilities such as panoramas, HDR, and video. Ben also explores workflow issues, including editing, sharing, and printing photos and transferring them to a computer.
